[comp.sys.ibm.pc] Breakthru 286 accelerator card

neff@hpvcla.HP.COM (Dave Neff) (12/22/86)

I bought a Breakthru board last September. I too  have been
pleased with it.  I also had some hard disk problems with the
first board, a minor problem with a second board, but the third
board is working fine.  I think the product was released a bit
prematurely, but PCSG has been a pleasure to work with.  They
were helpful, never hassled me about returning boards, and
their engineers followed up on a couple problems I found with
early boards. Their "Lightning" disk caching program is very
useful if you have an EMS board, and it automatically
"slows down" (technically it disables caching) when accessing
the floppy disk, eliminating most of the timing loop in ROM
hassles.  The product they are now shipping seems quite
solid.

At $395 its one of the better buys.  Of course if you use a
math coprocessor you have to buy an 80287 (5 or 8 MHZ) which
will effectively add a couple hundred to the price.  I have
read, however, that the "FAST 88" product is perhaps
the best bang for your buck (it ups the motherboard clock
speed but keeps the IO clock speed the same) and gives near
AT performance, but I didn't go that route.

The Breakthrough board runs at 8MHZ, has 16K of cache (most
other boards have only 8K), and several other good performance
oriented features for byte addressing and writing data to RAM.
It comes with a 60 day money back guarantee and a 1 year
warantee.

Normal disclaimers ....
